Assembly
ƒ Connect power supply modules, capacitor modules (optional), axis modules,
RFI filters and mains choke with earthed mounting plate with a surface as
large as possible
– Mounting plates with conductive surfaces (zinc−coated or stainless steel)
allow permanent contact.
– Painted plates are not suitable for the installation in accordance with the
EMC.
ƒ Use of capacitor module ECSxK...:
– Install the capacitor module between the power supply module and the
axis module(s).
– If the overall cable length in the DC−bus connection is > 5 m, install the
capacitor module as close as possible to the axis module with the greatest
power.
ƒ Use of several mounting plates:
– Connect as much surface as possible of the mounting plates (e.g. with
copper bands).
ƒ Ensure the separation of motor cable and signal or mains cable.
ƒ Do not use the same terminal strip for mains input and motor output.
ƒ Lay the cables as close as possible to the reference potential. Freely
suspended cables act like aerials.
Filters
Use RFI filters and mains chokes which are assigned to the power supply modules:
ƒ RFI filters reduce impermissible high−frequency interferences to a
permissible value.
ƒ Mains chokes reduce low−frequency interferences which mainly depend on
the motor cable and its length.
